    • A high-temperature direct-contact thermal energy storage element for use in a system for storage and retrieval of thermal energy in the range of about 400.degree. to about 3000.degree. F. The thermal energy is directly stored, without heat exchange tubes in composite latent/sensible heat thermal energy storage media utilizing the heat of fusion and high-temperature stability of alkaline metal and alkaline earth carbonates, chlorides, nitrates, nitrites, fluorides, hydroxides and sulfates and metal, metallic alloys and mixtures thereof maintained within a porous support-structure material which itself is capable of storage as sensible heat. The thermal energy storage according to the invention may be effectively utilized for storage of thermal energy derived from solar, industrial waste, process heat, and high-temperature gas reactor energy sources and retrieved for a wide variety of uses such as combustion air preheating, drying, space heating, heating of process gases, power generating heat engines and the like.

    • This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Moreover, additives, whether used alone or in combination, (1) can be admixed with the permeable mass, (2) can be mixed or alloyed with the parent metal, (3) can be placed at an interface between the parent metal and the preform or mass of filler material, (4) or any combination of the aforementioned methods, to modify properties of the resultant composite body. Particularly, additives such as VC, NbC, WC, W.sub.2 B.sub.5, TaC, ZrC, ZrB.sub.2, SiB.sub.6, SiC, MgO, Al.sub.2 O.sub.3, ZrO.sub.2, CeO.sub.2, Y.sub.2 O.sub.3, La.sub.2 O.sub.3, MgAl.sub.2 O.sub.4, HfO.sub.2, ZrSiO.sub.4, Yb.sub.2 O.sub.3 and Mo.sub.2 B.sub.5 can be combined with the permeable mass in an amount of about 5-50 percent by weight, prior to reactively infiltrating the permeable mass. Moreover, an additive may also include substantially pure elemental metals (e.g., Nb, Ti, Hf, V, Ta, Cr, Mo, Al, Cr, Si, Co and W) which may be provided by any of the methods discussed above herein.
